Specification of Letters Patent.

Application filed November 10,1905- Serlal No. 286,676.

To all whom it may concern.-

Be it known that I, JULIAN H. PrrKIN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement inEar-Retarders for Corn-Hus'kingMachines, of which the following is a complete specification.

This invention relates to means for presenting and retaining the ears ofcorn in proper relation With respect to the bushing-rollers operatingupon them, the object being to pro vide improved. means for suchpurpose.

Referring to the accompanying drawings, Figure 1 represents a plan viewof the husking-rolls and adjacent parts of a corn-husking machine inconnection with which the present invention is shown. Fig. 2 is a sideelevation of a pair of bushing-rollers with the earretarders inoperative relation therewith. Fig. 3 is a transverse section taken asindicated by the line 3 3 in Fig. 1. Fig. 4 is an enlarged detailsection showing the construc tion of the hinge-joint in theear-retarders, and Fig. 5 illustrates a modified construction of thesupport for the ear-retarders.

In the drawings, 1 designates a portion of the longitudinal sills of acorn huskerand shredder, and 1 the cross-bars, and in suitable bearings2 thereon are mounted the several pairs of husking-rolls 3 and 3. Thehusking-rolls 8 and 3 are grouped in pairs, one of the rollers 3 of eachpair being placed, as is common in such devices, in a plane slightlybelow its cooperating rolls 3. The rollers may be driven in any suitablemanner. The shafts of the rolls 3 are extended and provided at theirends with the bevelgears 4, which meshwith and are driven by thebevelgears 5 on the cross-shaft 6.

Between the several pairs of husking-rolls are secured thelongitudinally-extending angle-bars 7, which not only constitutesupports for the ear-retarders 8, but also form braces for thecross-bars 1 and shields to keep the ears of corn from lodging betweenthe several pairs of rolls. Other constructions of support for theear-retarders could be used-for instance, such as shown in Fig. 5, inwhich the support 7 is located some distance above the rolls, and theear-retarder is made to bend upwardly and engage same.

The ear-retarders 8 are formed of downwardly-projecting elastic stripsor blades secured to the angle-bars 7, twisted and defiected inwardly,as shown. The blades are twisted to conform approximately to thecurvature of the lower rolls, over which they extend and in such amanner as to present a flat surface at their extremity to the ears ofcorn, which it presses against the face of the rollers. The blades form,in effect, sections of a helix, of a very extended pitch. Their functionis to deflect the ears of corn between cooperating pairs of rolls tocompel them to slide singly down said rolls and to press the ears intopositive engagement therewith. From an inspection of Fig. 2 it will beseen that the rolls are placed, as is customary in this class ofmachines, at an inclination suflicient to cause the ears to slide bygravity along their course.

In order to render the lower or free ends of the blades of theear-retarders more yielding, the lower portions 8 of said blades arehingeconnected and spring-held to the upper or more rigid portion, thepin 9 forming the axis of the hinge-joint and the spring 10 permittingthe blade 8 to yield upwardly.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a corn-husking machine, in combination, a pair of husking-rollers,suitable bearings in which said rollers are j ournaled, downward andinwardly inclined elastic ear-retarders arranged above saidhusking-rollers, said ear-retarders .being twisted to a helical shape toconform to the husking-roller over which it is placed and presenting atits extremity a flat surface to the ear operated upon, and suitablesupports for said ear-retarders, substantially as and for the purposespecified.

2. In a corn-husking machine, in combination, a pair of husking-rollers,suitable bearings in which said rollers are journaled, earretardersupports located adjacent to said rollers, and downwardly and inwardlyprojecting ear-retarders secured to said supports, said ear-retarderscomprised of an upper rigid portion and a lower spring-held bladehingeconnected therewith, substantially as and for the purposespecified.

3. In a corn-husking machine, in combination, a pair of husking-rollers,suitable bearspring-held blade hinge-connected therewith, ings in whichsaid rollers are j ournaled,'ear substantially as and for the purposespecified retarder supports located adjacent to said PITKIN L rollers,and downwardly-projecting twisted 5 and inwardly-deflected ear-retarderssecured Witnesses:
